Chapter 11 Firewall
Your customized rules take precedence and override the ZyWALL's default settings. The
ZyWALL checks the source IP address, destination IP address and IP protocol type of network
traffic against the firewall rules (in the order you list them). When the traffic matches a rule,
the ZyWALL takes the action specified in the rule.

11.2 Packet Direction Matrix

The ZyWALL's packet direction matrix allows you to apply certain security settings (like
firewall) to traffic flowing in specific directions.
For example, click SECURITY > FIREWALL to open the following screen. This screen
configures general firewall settings.
